CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and benefit of U.S. provisionalpatent application Ser. No. 61/123,930, filed Apr. 11, 2008, thespecification of which is incorporated herein in its entirety.

FIELD OF THE INVENTION

The present invention relates to hand operated portable devices forgrasping and manipulation of objects. More specifically, the inventioncomprises adjustable length devices for grasping and manipulation ofobjects, e.g., by persons with limited physical ability due to age,weakness, or the like, and/or for grasping and manipulation of objectsout of normal/easy reach of persons.

BACKGROUND OF THE INVENTION

Many persons need the ability to grasp and manipulate objects that arenormally out of their reach or that would otherwise be inconvenient ordifficult to reach. For example, picking up objects on the ground or onhigh shelves can often be problematic. Such needs are even greater forpersons having limited physical ability (e.g., due to age or infirmity).Such persons can have limited gripping ability or hand strength or canhave limited bending or stretching ability, thus, leading to greaterneed for help in picking up or reaching objects.

While a number of devices have been developed to help inreaching/picking up objects, such prior work has been lacking in anumber of areas. For example, such devices are of a fixed length whichcan limit their usability. Furthermore, such devices typically include adirect correspondence between the distance the trigger is moved by theuser and the distance moved by the gripping portion of the device. Suchcorrespondence, thus often requires a large hand movement to completelygrasp small objects. Furthermore, such devices typically requireconstant pressure to keep the object grasped within the device. Variousembodiments of the present invention address the above and other issuesand provide novel adjustable length devices for grasping and/ormanipulation of objects. The current invention also provides additionaladvantages which will be apparent upon reading of the description,claims, and figures herein.

SUMMARY OF THE INVENTION

In various aspects, the current invention comprises an adjustable lengthdevice for grasping and/or picking up objects.

In one group of embodiments herein, the invention comprises anadjustable length pick up device for grasping an object wherein thedevices comprise a head region comprising two opposing jaw members, atube region that is operably connected to the head region and, a handleregion that is operably connected to the tube region and which comprisesa trigger mechanism. In some such devices, the tube region comprises anadjustable length and squeezing the trigger causes the jaw members tomove towards each other. Also, in some such embodiments, the tube regioncomprises a telescoping tube. Also, in some of such embodiments, thetube region comprises: a cable that is operably connected to thetrigger; a toothed rod that has a plurality of teeth and that isoperably connected to the jaw members; and a toothed rod lockingmechanism (TRLM) that is operably connected to the cable, whereinsqueezing the trigger causes the TRLM to operably engage with thetoothed rod. Furthermore, in some of such embodiments, the head regioncomprises two opposing angled jaw members, each of which jaw memberscomprises a proximal end and a distal end, and each of which jaw membersis operably attached at a pivot point to a jaw base assembly, thusallowing movement of each jaw member around its pivot point; wherein theproximal end of both jaw members operably interacts with a jaw actuatorwithin the jaw base assembly, which jaw actuator is operably connectedto an actuator rod and a jaw actuator spring and wherein the actuatorrod is operably connected to the toothed rod; wherein the handle regioncomprises a handle body having a base, a trigger, and a linkage leverhaving a free end wherein the cable is operably coupled to the free endof the linkage lever; and, wherein squeezing the trigger causes thelinkage lever to extend towards the base of the handle body, thuscausing the cable to move proximally in the handle body and in the tuberegion and causing the TRLM to operably engage with the toothed rodwhich thereby causes the toothed rod to move proximally in the tuberegion, thus causing the jaw actuator rod and jaw actuator to moveproximally, which in turn, draws in the proximal end of each jaw member,thus causing each jaw member to move around its pivot point and causingthe distal ends of the opposing jaw members to move towards one another.Also, in some such embodiments, the TRLM comprises a lever (which cancomprise one or more teeth which can mate with the teeth of the toothedrod), which lever is operably controlled by the trigger via the cable,wherein squeezing the trigger causes the lever of the TRLM to operablyengage with the toothed rod and wherein releasing the trigger causes thelever to operably disengage with the toothed rod.

In another group of embodiments the device comprises a head regionhaving two opposing jaw members with each member having a proximal end(i.e., an end closer to the handle end and closer to the user of thedevice when it is held by the handle) and a distal end (i.e., the endfurther from the handle), and each of which jaw members is operablyattached at a pivot point to a jaw base assembly. Such attachment, thus,allows movement of each jaw member around its pivot point. In suchembodiments, the proximal end of both jaw members operably interactswith a jaw actuator within the jaw base assembly (typically by insertinginto the actuator). In turn, the jaw actuator is operably connected toan actuator rod and a jaw actuator spring (which helps in holding openthe jaw members, e.g., when the trigger is not being squeezed or when itis optionally locked). Such embodiments also comprise an elongatedhollow tube region made of two or more hollow tube subparts of differingdiameter, one of which can be slid into the interior of the other (whichallows for adjustment of the overall length of the hollow tube/shaftregion) and which enclose a toothed rod, toothed rod locking mechanism,and cable that are operably connected to the actuator rod (via thetoothed rod). Also, such embodiments comprise a handle region comprisinga handle body, an optional latch mechanism (e.g., latching lever, latchcable, latch, latching spring, etc.), and a trigger grip with a linkagelever (i.e., a leverage action trigger) that has the cable operablycoupled to its free bottom end. In such embodiments, by squeezing thetrigger the linkage lever can be caused to extend downwards in thehandle body towards the handle base, which pulls the cable, the toothedrod locking mechanism, and the toothed rod proximally in the handle bodyand in the tube region. The movement of the cable and toothed rod, etc.,thus causes the jaw actuator rod and jaw actuator to also moveproximally, which in turn, draws in the proximal end of each jaw memberand causes each jaw member to move around its pivot point so that thedistal ends of the opposing jaw members move towards one another.

In the various embodiments herein, the jaw actuator spring can exertpressure against the proximal end of the jaw actuator thus causing thedistal ends of the jaw members to pivot away from each other as the jawactuator is pushed distally. Such pressure helps in keeping the jawmembers open (extended away from each other) when the trigger/linkagelever is not squeezed and/or locked.

In some of the various embodiments herein, the devices comprise anoptional latch mechanism which comprises a spring loaded latch that isoperably attached to a latch cable, which, in turn, is operably coupledto a latching lever. The latch mechanism, when set (or engaged),reversibly locks the trigger/linkage lever, thereby reversibly lockingthe jaw members at a desired position. Additionally, in some suchdevices having the optional latch mechanism, expansion of the componentswithin the device such as the toothed strap and/or cable, etc., (e.g.,when pressure is applied on it from the trigger/linkage lever via thecable) allows the trigger to be squeezed further in, even when the jawmembers cannot move closer together (e.g., when an object is beinggrasped by the device). Such expansion thus allows the optional triggerto move far enough into the handle body so that if the latching lever isset, the spring loaded latch will engage and prevent the jaw membersfrom opening.

In the various embodiments, the devices of the invention can have jawmembers that comprise a textured inner surface layer and/or whichcomprise a pad area at their proximal tips.

In some of the various devices herein, movement of the trigger can causea movement of the jaw members over a greater distance than that moved bythe trigger (assuming that the jaws are allowed to freely move and arenot blocked, etc.).

Also, in some of the various devices herein the handle body can comprisea palm rest area that comprises a thermoplastic rubber and/orthermoplastic elastomer overlay on the handle body. Such rest area islocated so as to improve user comfort and performance by, e.g., reducingslipping, adding in durability and increasing aesthetics.

In certain of the various embodiments, the head region of the device canbe rotated in relation to the tube region and handle region, and securedin one or more orientations, e.g., by the interaction of fluted orgrooved areas within the tube region and raised protuberances on theinner lumen of the proximal opening of the jaw base assembly.

In other aspects, the invention comprises a method of grasping and/orpicking up an object by first situating two opposing angled jaw membersof the head region of an adjustable length pick up device around theobject, wherein the device also comprises a tube region operablyconnected to the head region and a handle region operably connect to thetube region, which handle region comprises a trigger mechanism and thensqueezing the trigger which causes the jaw members to move towards eachother and thus grasp and/or pick up the object. In some suchembodiments, the tube region can comprise a telescoping tube. Also, insome such methods the tube region can comprises: a cable that isoperably connected to the trigger; a toothed rod comprising a pluralityof teeth which toothed rod is operably connected to the jaw members; anda toothed rod locking mechanism (TRLM) that is operably connected to thecable wherein squeezing the trigger causes the TRLM to operably engagewith the toothed rod which causes the jaw members to move towards eachother and thus grasp and/or pick up the object. Furthermore, in somesuch embodiments, the head region can comprises two opposing angled jawmembers, each of which jaw members comprises a proximal end and a distalend, and each of which jaw members is operably attached at a pivot pointto a jaw base assembly, thus allowing movement of each jaw member aroundits pivot point; wherein the proximal end of both jaw members operablyinteracts with a jaw actuator within the jaw base assembly, which jawactuator is operably connected to an actuator rod and a jaw actuatorspring and wherein the actuator rod is operably connected to the toothedrod wherein the handle region comprises a handle body having a base, atrigger, and a linkage lever having a free end wherein the cable isoperably coupled to the free end of the linkage lever; and, whereinsqueezing the trigger causes the linkage lever to extend towards thebase of the handle body, thus causing the cable to move proximally inthe handle body and in the tube region and causing the toothed rodlocking mechanism to operably engage with the toothed rod which therebycauses the toothed rod to move proximally in the tube region, thuscausing the jaw actuator rod and jaw actuator to move proximally, whichin turn, draws in the proximal end of each jaw member, thus causing eachjaw member to move around its pivot point and causing the distal ends ofthe opposing jaw members to move towards one another and thus graspand/or pick up the object. In some such embodiments, the TRLM comprisesa lever (which can comprise one or more teeth that are capable of matingwith the teeth of the toothed rod), which lever is operably controlledby the trigger via the cable, wherein squeezing the trigger causes thelever of the TRLM to operably engage with the toothed rod and whereinreleasing the trigger causes the lever to operably disengage with thetoothed rod.

In other aspects the invention comprises methods of grasping and/orpicking up an object with an adjustable length pick-up device.Embodiments of such methods comprise selecting an appropriate length atwhich to set the tube/shaft region of the device (and setting it atsuch), situating two opposing angled jaw members of the device aroundthe object, each of which jaw members comprises a proximal end and adistal end, and each of which jaw members is operably attached at apivot point to a jaw base assembly (which allows movement of each jawmember around its pivot point). In such methods, the proximal end ofboth jaw members operably interacts with a jaw actuator (within the jawbase assembly) that is operably connected to an actuator rod. The deviceused in such method embodiments also comprises an adjustable lengthelongated hollow tube region, enclosing a toothed rod, a toothed rodlocking mechanism, and a cable that are operably connected to theactuator rod. Additionally, the devices in such method embodiments alsocomprise a handle region comprising a handle body, an optional latchmechanism, and a trigger grip having a linkage lever, wherein the cableis operably coupled to the bottom of the linkage lever. In variousembodiments, after the object is situated, the trigger is squeezedcausing the linkage lever to extend downwards in the handle body. Suchextension causes the cable and toothed rod/toothed rod locking mechanismto move proximally and causes the jaw actuator rod and jaw actuator tomove proximally. The movement of the jaw actuator, in turn, draws in theproximal end of each jaw member which causes each jaw member to movearound its pivot point and causes the distal ends of the opposing jawmembers to move towards one another and thus grasp and/or pick up theobject.

In yet other aspects, the invention comprises methods of grasping and/orpicking up an object by situating two opposing jaw members of anadjustable length device around the object (which members are operablyattached at pivot points to a base assembly and to a jaw actuator) andsqueezing a trigger of the device (which trigger moves a linkage leverand which linkage lever is operably coupled, directly or indirectly, tothe opposing jaw members), thereby moving the jaw members towards oneanother and grasping the object.

In another group of embodiments herein, the invention comprises anadjustable length device to operably connect at least two components.Such devices comprise: a cable having a first end and a second end, arod having a first end and a second end, and a locking mechanismoperably attached to the cable, wherein the locking mechanism comprisesa movable lever, which lever is controllably engaged or disengaged bymovement of the cable. In such devices, the locking mechanism can bemoved along the rod when the lever is disengaged and is stationary whenthe lever is engaged. Also, such devices can comprise a tube that isadjustable in length and the rod can comprise a toothed rod and thelever can comprise one or more teeth that are capable of mating with theteeth of the toothed rod. In such embodiments, the cable can connect toa trigger mechanism wherein squeezing the trigger mechanism engages thelever with the toothed rod (that can be operably connected to one ormore additional components such as a pair of opposable jaw members).

These and other devices and methods of the invention will become morefully apparent when the following detailed description is read inconjunction with the accompanying figures and claims.

DETAILED DESCRIPTION

Before describing the present invention in detail, it is to beunderstood that this invention is not limited to particular embodiments,which can, of course, vary. It is also to be understood that theterminology used herein is for the purpose of describing particularembodiments only, and is not necessarily intended to be limiting. Asused in this specification and the appended claims, terms in thesingular and the singular forms “a,” “an,” and “the” include pluralreferents unless the context clearly dictates otherwise. Thus, forexample, reference to “a pick up device” also includes a plurality ofpick up devices, “a tooth” also includes a plurality of teeth, and thelike.

Various exemplary embodiments of the present invention are illustratedin the accompanying figures. General perspective views of adjustablelength pick up devices are shown in FIGS. 1 (with a latching mechanismto hold the jaws in place) and 2 (without a latching mechanism to holdthe jaws in place). For purposes of description and illustration, thevarious adjustable length pick up devices of the invention, e.g., pickup device 100 in FIG. 1 or in FIG. 2, can roughly be considered in threesections. Thus, the device comprises a head region comprising twoopposing jaws, Region A; an adjustable length tube (or shaft) region,Region B, comprising an extendable/adjustable elongated tube(s) orhollow structure(s); and a handle region, Region C, comprising a handle,a trigger, and an optional jaw locking (or latching) mechanism.

While the elements in each section are generally discussed separatelyherein, it will be appreciated that such description should not be takenas limiting upon either the devices or uses/operation of the inventionor upon the interaction or connectivity of the elements of theinvention. Thus, it will be appreciated that various aspects of theembodiments shown in particular Figures (e.g., the linkage levercomponents in FIG. 20 or 24) can be applicable to the variousembodiments of the telescoping pick up devices even though thecomponents of FIG. 20 or 24 are not shown in every figure, etc.

Telescoping Tube Region

One of the benefits of the embodiments of the current invention is thatthe overall length of the devices can be adjusted by changing the lengthof the telescoping tube region. See Region B in FIG. 1. Because of theadjustable lengths, the embodiments of the invention can be used in awider array of settings, e.g., they can be used to more convenientlygrasp items over a wider range of distances.

It will be appreciated that the various embodiments of the invention canoptionally comprise different components in order to allow adjustment inlength of the device and that recitation of particularcomponents/configurations, etc., should not necessarily be taken aslimiting. Thus, for example, some embodiments can comprise a toothed rodlocking mechanism (TRLM) lever with one tooth, while other embodimentscan comprise a lever with two teeth, etc. See below.

It will also be appreciated that the telescoping mechanism (e.g., thetelescoping tubes/shafts and their internal components, etc.) of thepick up devices herein can optionally be used with other non-pick updevices or with other types of pick up devices than those describedherein. Thus, the telescoping components of the devices herein can alsobe applicable to telescoping devices used to, e.g., cut or trim items(as in pruning shears), to move an item (as in a paintbrush, etc.) orthe like.

As can be seen in FIGS. 1 and 2 in adjustable length pick up devices ofthe invention, interacting hollow tubes 135 and 136 connect the headregion of the device with the handle region of the device. The hollowtubes comprise at least two subparts (e.g., distal tube 135 and proximaltube 136 as shown in FIGS. 1 and 2). Of course, it will be appreciatedthat other embodiments of the invention can comprise a greater number oftube subparts, e.g., 3, 4, 5, 10, 20, or more. In general, components ofthe devices herein are described as distal or proximal depending upontheir spatial relation with the handle of the device, with “distal”components being further from the handle and “proximal” components beingcloser to the handle. In particular embodiments, one subpart of thetelescoping tube or shaft region is of smaller overall diameter than thelumen opening of the other subpart, thus allowing the smaller subpart toslide into the wider subpart (e.g., the distal tube can slide into theinterior of the proximal tube). See, e.g., FIGS. 8, 12, and 13. It willbe appreciated that while in the present description the distal tube isshown as a smaller diameter than the proximal tube (and thus capable ofsliding within the proximal tube), in some embodiments, the reverse istrue. In other words, in some embodiments, the proximal tube is ofsmaller diameter, and can slide into, the distal tube. Because thesmaller diameter tube can be inserted into the larger tube, the overalllength of the hollow tube can thus be adjusted.

In various embodiments, the ends of the telescoping tubes mate with theproximal end of the jaw base assembly (meeting point 131) and with thedistal end of the handle (meeting point 144). In certain embodiments,the ends of the tubes are inserted within the jaw base assembly and thehandle. The ends of the jaw base assembly and the handle can havespecific diameters at such mating points so that the tubes fit snuglytherein. See, e.g., FIGS. 5, 7, 19, 20, 23, etc. The telescoping tubecan be held in place with the jaw base assembly and with the handle byfriction, by glue or adhesive, by spot welds, by crimping, by screws,bolts, clamps, or the like, or by any combination thereof. The subpartsof the telescoping tubes can be of different lengths and diameters indifferent embodiments, thus, allowing different embodiments to havedifferent possible overall adjustable lengths possible.

In particular telescoping embodiments, one or more of the interlockingtubes can comprise fluting, or grooves, on their shafts (e.g., groove1200). See below and FIGS. 2, 3, 8, 12, 17, etc. In such embodiments,the tubes can comprise, e.g., two grooves opposite each other on eitherside of the tube. The flutes in the tubes can, e.g., add structuralintegrity and/or strength to the telescoping tube and/or aid instability and orientation of the telescoping pieces. For example, insome embodiments, the flutes of the distal tube can mate with flutes ofthe proximal tube. In some embodiments, only one part of the telescopingtube comprises fluting, e.g., in some embodiments, only the distal tubecomprises fluting while the proximal tube does not or in someembodiments, only the tube that slides inside the other tube has flutes.As seen in the figures, various components within the tube/shaft, e.g.,the toothed rod locking mechanism (TRLM), the distal plate, the floatingplate, the proximal plate, etc., can also be fluted to match the flutingof the tube/shaft. See, e.g., FIGS. 6, 8, 9, 18, etc. The fluting canalso help guide such internal mechanisms (e.g., those for thetelescoping aspect and/or those for movement of the jaws). Such flutingalso can add decorative interest and can in certain embodiments, aid inrotation of the head region around the shaft. See below.

In various embodiments, the telescoping tubes are constructed from orcomprise, e.g., metal (e.g., aluminum, anodized aluminum, steel,stainless steel, iron, magnesium, magnesium alloy, or various metallicalloys), plastic (e.g., a polycarbonate, a polyvinyl, a thermoplastic, athermoplastic elastomer, a thermoplastic rubber, a polyoxymethylene,Lexan®, Delrin®, etc.), ceramic, polymer, resin, or any combinationsthereof. In certain embodiments, the tubes comprise anodized aluminum,while in other certain embodiments, the tubes comprise polyoxymethylene,Lexan, and/or Delrin.

In the various embodiments herein, the action of the trigger from thehandle region is operably connected to movement of the jaws of thedevice via a mechanism (e.g., within the telescoping tube region) thatcan controllably connect and disconnect the trigger and the jaws. Forexample, the mechanism can operably connect the trigger and the jawswhen the trigger is squeezed and disconnect the trigger/jaws when thetrigger is not squeezed. The action of such mechanism is independent ofthe overall length of the telescoping tube region. It will beappreciated that while particular components and configurations ofvarious embodiments of the mechanism for the operable connection betweenthe trigger action and the jaw movement are depicted herein, suchrecitations should not necessarily be taken as limiting. Thus, inparticular embodiments herein, the mechanism that operablyconnects/disconnects the trigger and the jaws of the device comprises atoothed rod locking mechanism (TRLM). Thus in some embodiments, a TRLMcan operably connect/disconnect a cable (which in turn is operablyattached to the trigger via the linkage lever) and a toothed rod (whichin turn is operably connected to the jaws via the actuator rod).

In particular embodiments, a toothed rod, e.g., toothed rod 590 in FIG.5, connects the actuator rod (e.g., rod 351 in FIG. 3) with a cable,e.g., cable 660 or similar, via a toothed rod locking mechanism (ortoothed rod gripping mechanism), e.g., toothed rod locking mechanism(TRLM) 640. Thus, in such embodiments, the mechanism that operablyconnects the trigger action and the jaw movement comprises a TRLM (e.g.,TRLM 640). Such interaction between the toothed rod, the TRLM, and thecable allows a user of the device to close the device's jaws by pullingthe trigger. However, because such interaction is released when thetrigger is released (assuming that the jaws are not locked with anoptional jaw latching mechanism), the length of the hollow tube or shaftcan also be adjusted. See below.

In certain embodiments, at its distal end, the toothed rod attaches tothe actuator rod in the jaw base assembly. See, e.g., FIGS. 5 and 6. Itwill be appreciated that the interaction of the actuator rod and thetoothed rod can occur within the jaw base assembly or within thetelescoping tube region, depending on the embodiment. The toothed rodcan attach to the actuator rod in a number of ways. For example, thetoothed rod can bifurcate around the proximal end of the actuator rod(forming bifurcation area 610) and be connected via pin 876 or othersimilar connection at pin location 575. At its proximal end, the toothedrod is typically unattached and can freely move distally and proximallyin the tube region. See, e.g., FIGS. 8, 19, etc. In some embodiments,the proximal end of the toothed rod is flanged (see FIG. 19), e.g., tohelp prevent the toothed rod from being pulled too far out (distally).The flanges can prevent the toothed rod from being pulled all the waythrough the TRLM. In other embodiments, the proximal end of the toothedrod can comprise a pin (such as pin 811) which is wider than the widthof the end of the toothed rod and which is also wider than the openingin the TRLM (e.g., opening 1620) through which the toothed rodtraverses, thus also preventing the toothed rod from being pulled toofar out. In between its two ends, the toothed rod traverses the toothedrod locking mechanism (TRLM). As will be appreciated, the location ofthe TRLM on the toothed rod can vary as the length of the telescopingtube is adjusted. Thus, when one telescoping tube is pushed inside theother one (i.e., to in order to decrease the overall length of thedevice), the TRLM interacts with the toothed rod at a point closer tothe distal end of the toothed rod, while when the telescoping tube isextended, the TRLM interacts with the toothed rod at a point closer tothe proximal end of the toothed rod.

As can be seen in FIGS. 5, 6, 9, 14, etc., the toothed rod canoptionally have teeth or similar crenellations in order to interact withthe TRLM. As explained in more detail below, the toothed rod and theTRLM can interact via a TRLM lever. In the various embodiments havingteeth or ridges/crenellations on the toothed rod, such teeth can be ofdifferent depth (i.e., one embodiment can have teeth that have a greaterdistance from their tips to their troughs than another embodiment), canbe of different shape (e.g., teeth can be wide and shallow, teeth can besteep and thin, etc.). Furthermore, in some embodiments, the toothed rodcan comprise outer sidewalls. See, e.g., FIG. 6. However, as shown inFIG. 14, the teeth or crenellations of the toothed rod can also be“open” or not bounded by sidewalls. Also, while the toothed rod istypically described herein as comprising teeth, in yet otherembodiments, the rod can comprise a ladder conformation or the like. Insuch ladder embodiments, the rod does not comprise teeth, but rather hasshaped openings (e.g., ladder-like) that can mate with one or more toothor other protuberances from the lever in the TRLM. Also, while primarilyshown in the accompanying figures as square, it will be appreciated thatin various embodiments, the toothed rod can have a square, rectangular,triangular, round, oval, or other shaped cross-sectional profile.Furthermore, in various embodiments, the toothed rod can comprise teethon more than one surface, e.g., on opposing surfaces of a square rod, onall surfaces of a square rod, on all surfaces of a triangular rod, asencircling ridges on a round or oval rod, etc. The teeth on the toothedrod can also be of any orientation, e.g., the teeth can be slantedtowards the jaws or towards the handle of the device, or the teeth canbe symmetrical (not slanted). Of course, in typical embodiments, theteeth of the toothed rod are designed to mate with teeth on the TRLMlever and are typically oriented to “grab” onto and “hold” the teeth onthe TRLM lever when the lever is engaged (e.g., when the trigger of thedevice is activated). See below.

The toothed rod fits into an opening in the TRLM (e.g., opening, 1620)and traverses through the TRLM as can be seen in, e.g., FIGS. 7, 16,etc. In typical operation of the devices of the invention, the toothedrod can be controllably moved through such opening, e.g., when thetelescoping tube is expanded or contracted.

The TRLM is held in place in the telescoping shaft by placement orstabilizer rods, such as stabilizer rods 680. Such stabilizer rods keepthe TRLM in proper placement and orientation without it having to beconnected to the inside wall of the proximal or distal shaft. Because ofthis “free floating” aspect of the TRLM, the proximal end of the distalshaft can be inserted into the distal end of the proximal shaft tovarying amounts, thus allowing the overall length of the shaft area tobe adjusted. See, e.g., FIGS. 12 and 13. In certain embodiments, theTRLM is placed far enough distally in the telescoping tube such that itis present in the “overlap” area, i.e., the area where the proximal endof the distal tube is still within the distal end of the proximal tubeeven when the telescoping tube is extended to its greatest length.

The TRLM typically comprises a body shaped to fit within the tubes ofthe telescoping tube region (e.g., shaped to fit within the smaller ofthe two tubes) and comprises components to allow a TRLM lever or similarcomponent (which in turn is attached to a cable that is operablyattached to the linkage lever in the handle) to connect with anddisconnect with the toothed rod (which in turn is operably connected tothe actuator rod and jaws of the device). Various embodiments of TRLMsare shown in, e.g., FIGS. 6, 14, 16, etc. Cut away views of the TRLM areshown in, e.g., FIGS. 7, 10, 12, 13, etc., while internal pieces of aTRLM are shown in FIGS. 11 (in place within the tube but without theTRLM body) and 14. Thus, in particular embodiments, the TRLM comprises abody (e.g., TRLM body 640), which has a opening that traverses itthrough which the toothed rod moves (e.g., opening 1620), openings forthe stabilizer rods to traverse through the body (e.g., openings 1630),one or more flutings on the surface of the body which mate with theflutings in the telescoping tube (e.g., in the proximal and/or distaltube), an open space for the TRLM lever to fit within the body of theTRLM where the lever can operably interact with the toothed rod (opening1610), a hole for the lever pivot pin (e.g., pin 1120) to be placed, anopening for the cable from the trigger to enter the TRLM (e.g., opening900), a TRLM lever (e.g., lever 1100) which is described in more detailbelow, and a lever spring (e.g., 1110) which is also described in moredetail below.

As stated, the TRLM lever can controllably interact with the toothed rodthat traverses through the TRLM. In particular embodiments, the TRLMlever comprises one or more teeth that can operably interact with theteeth of the toothed rod, thereby holding the toothed rod in place whenthe teeth are engaged. As mentioned above, the TRLM can also compriselever spring 1110, which acts to help disengage the TRLM lever (e.g.,the teeth of the lever) from the teeth of the toothed rod when thetrigger of the device is not being squeezed. In various embodiments theTRLM lever can comprise one tooth, two teeth, three teeth, or four ormore teeth. It will be appreciated that in typical embodiments, theshape of the part of the TRLM lever that interacts with the toothed rodis configured to mate with the toothed rod. Thus, teeth on the TRLMlever can be of corresponding shape, depth, angle, etc. as teeth on thetoothed rod so that they mate. See above. FIG. 16B illustrates severalaspects of an example TRLM lever of the invention. TRLM lever 1100 isshown, as is opening 1650 where pivot pin 1120 enters (Cf. opening 1600in TRLM body in FIG. 16A), opening 1640 where cable 660 passes throughthe lever, indentation 1660 where lever spring 1110 rests, and toothridges 1670 which mate with troughs in toothed rod 590. FIG. 15illustrates several alternate embodiments of TRLM levers and toothedrods. FIG. 15B shows two embodiments each having two TRLM levers thatinteract with a toothed rod having a square cross-section and that hasteeth on at least two sides. In one such embodiment, one cable interactswith both levers, while in the other embodiment, each lever has its owncable. Correspondingly, the cables shown in FIG. 15B for the embodimentwith two cables, can both arise through bifurcation from the same cable(i.e., a third cable) which in turn connects to the linkage lever, etc.,or each cable can be completely separate all the way to the connectionon the linkage lever. FIG. 15C shows a cut away view of an embodimentcomprising a circular lever (or collaret) which encircles a toothed rodthat has a circular cross section and teeth all the way around the rod.It will be appreciated that the lever springs in the embodiment in FIG.15C are orientated differently than those in, e.g., FIG. 15A, etc., butserve the same purpose (e.g., to disengage the TRLM lever from thetoothed rod when the trigger is released). For purposes of clarity, inthe embodiments shown in FIGS. 15B and C, the TRLM body is not shown.FIG. 15A illustrates the operation of the TRLM lever on the toothed rodwhen pressure is applied on the attached cable. As explained, whenpressure is applied on cable 660 (because the trigger is squeezed), thecable pulls on lever 1100 which pivots at pin 1120 and engages it teethinto toothed rod 590.

As stated above, the TRLM is held in place in the lumen of thetelescoping tube by one or more stabilizer or holding rods. FIG. 9 showsstabilizing rods 680 surrounded by rod springs 670. In variousembodiments, at their distal ends, the stabilizer rods enter intoopenings in the TRLM, e.g., via openings 1630, and freely traversethrough the TRLM, while at their proximal ends they can be connected toa proximal plate, e.g., proximal plate 810 as in FIG. 18. In variousembodiments, the rod springs can extend the full length of thestabilizer rods from the proximal plate to the TRLM, while in otherembodiments, the rod springs can extend part of such distance, e.g.,from the TRLM to a stop ring such as stop ring 910 in FIG. 9.

In typical usage of the devices herein, the TRLM is pulled proximallywhen the trigger is pulled (because the trigger pulls the cable which isattached to the TRLM). The distal end of the cable can optionally bebulbous or can comprise some other feature that keeps it within theTRLM. See, e.g., cable end 710 in FIGS. 13-15. When the TRLM is pulledproximally along the rods by the cable, it the compresses rod springs.As explained further below, when the trigger mechanism is released thecable is no longer pulled, and the rod springs can then optionally actto push the TRLM distally back to its position before the trigger wasactivated.

FIG. 16A displays several perspectives of an example TRLM. FIG. 16Ashows TRLM body 640, along with opening 1610 where the TRLM lever islocated, opening 1600 where pivot pin 1120 fits, openings 1630 (which itwill be appreciated are present on both ends of the TRLM body) where thestabilizer rods traverse through the body, and opening 1620 where thetoothed rod traverses the body.

Also in the various embodiments of the invention, a cable (e.g., cable660) that is connected at its proximal end to the bottom of the linkagelever (i.e., the free end of the linkage lever closest to the handlebase) and at its distal end to the TRLM lever in the TRLM. In someembodiments, the cable can be, e.g., a strap, an articulated strap, awire, a woven wire, a braided wire, a chain, or other similar cable-likemember. In some embodiments, the cable can comprise attachment loop1400, or other similar configurations to aid in its connection to thelinkage lever. See below.

Some embodiments can also comprise various plates within the telescopingtube. For example, various embodiments of the invention include a distalplate, e.g., distal plate 390, attached around the toothed rod or aroundthe proximal end of the actuator rod (see, e.g., FIGS. 3, 6, etc.). Insome embodiments, the distal plate is placed around the proximal end ofthe actuator rod distal to the connection of the actuator rod and thetoothed rod (see, e.g., FIG. 5) while in other embodiments, the distalplate can be placed around the toothed rod and can optionally compriseteeth or threads to keep it secure around the toothed rod (see, e.g.,FIGS. 9 and 10). The various embodiments can also comprise a proximalplate (e.g., proximal plate 810) into which the stabilizer rods areattached and through which the proximal end of the toothed rod canoptionally traverse (see, e.g., FIG. 18). As shown in FIG. 18, proximalplate 810 can comprise openings 1810 to receive the stabilizer rods andan opening 1800 through which the cable travels from the handle into thetelescoping tube region. Furthermore, some embodiments can comprise afloating plate, e.g., floating plate 800 as in FIG. 8, which can help toguide the cable (e.g., cable 660) going to the TRLM and/or help keep thestabilizer rods and the rod springs properly orientated. Such floatingplates can be placed around the toothed rod between the TRLM and thehandle region. Various embodiments of the floating plate as shown inFIG. 18C can comprise fluting 1830 (which typically mates with thefluting of the tube, e.g., the smaller diameter tube), opening 1840through which the toothed rod is threaded, slot 1820 through with thecable is placed and guided, and indentations 1850 through which thestabilizer rods and their springs are guided.

The toothed rod, the stabilizer rods, the rod springs, the floatingplates, and the various components of the TRLM can be constructed fromany of a number of materials, e.g., metal (e.g., aluminum, anodizedaluminum, steel, stainless steel, magnesium, magnesium alloy(s), iron,metal alloys, and/or combinations thereof), plastic (e.g., apolycarbonate, a polyvinyl, a polyoxymethylene, Lexan, Delrin, etc.), athermoplastic, a thermoplastic rubber, a thermoplastic elastomer, etc.,ceramic, polymer, resin, wood, or any combinations thereof.

Tube locking mechanism 137 is shown as a threaded device in the Figuresherein. Of course, it will be appreciated that the tube lockingmechanism can alternatively comprise other formations to stably hold two(or more) joined shafts, which formations will be well known to those ofskill in the art (e.g., common arrangements such as for extendabletripods, etc.). In the Figures, tube locking mechanism 137 is comprisedof part 137 a (attached to the distal tube) and part 137 b (attached tothe proximal tube). As can be seen in FIG. 17, flanges 1710 areseparated by slits 1700 on tube locking mechanism part 137 b. When, part137 a is threaded onto part 137 b, it can optionally pinch the flangescloser together to therefore tightly grip onto the telescoping tubes.

In certain embodiments, the inner surface of the proximal end of the jawbase assembly (see, e.g., FIG. 5) can comprise one or more ridges,knobs, dots, or other similar raised protuberances that rest within (orbeside) the flute(s) in the shaft(s). For example, ridges 570 can beseen in FIG. 5. Such ridges, etc. can act to stabilize the head regionin a particular orientation in relation to the shaft. Furthermore,certain embodiments can comprise multiple ridges in the jaw baseassembly mated with multiple flutes within the shaft, while someembodiments can comprise a greater number of flutes than of ridges. Incertain embodiments, the jaw base assembly and the shaft are notpermanently affixed (e.g., they are not welded, glued together, etc.),but rather they are held together by, e.g., the presence and connectionsof the internal mechanism (e.g., the jaw actuator, jaw actuator rod,toothed rod, etc.), the friction between the tube and the jaw baseassembly, etc. Thus, in some embodiments, the internal connectionsthrough the shaft region allow play in length. Thus, the head region canbe pulled slightly out (e.g., away from the distal end of the distalshaft) so that the ridge(s) within the flute(s) stabilizing the headregion are removed from the flute(s). Thus, the head region can then berotated and then moved back towards the shaft so that the ridge(s)re-enter different flute(s) and stabilize the rotated head region in anew and different orientation in relation to the shaft/handle. It willbe appreciated that some embodiments comprise a plurality of flutes andridges thus allowing a fine degree of control over head rotation. Insome such embodiments, the actuator rod interacts with the jaw actuatorcap such that they do not prohibit rotation of the head region (e.g.,the activator cap freely circles around the jaw actuator rod, etc.).

In some embodiments, the user is unable to completely remove distal tube135 from proximal tube 136. While the head of the device can optionallybe pulled distally far enough to rotate, typically neither the headregion nor tube 135 are completely removable once assembled. Wingnuts orflanged components, e.g., flanges on the proximal end of the toothedrod, or pins on the proximal end of the toothed rod, can optionally keepthe toothed rod (and thus the head region and/or distal tube) fromcomplete removal. Such optional flanging, etc. can block such removal byinteraction with the TRLM, etc.

Again, within the telescoping tube, the toothed rod is attached at itsdistal end to the jaw actuator rod. Such attachment can be by hookarrangement or by pins, crimping, clipping, welding, adhesive/glue, orany other appropriate method. See, e.g., FIG. 8. In some embodiments,the toothed rod and the jaw actuator rod can be connected through one ormore intermediary(ies) (e.g., another cable, etc.) At its proximal end,the toothed rod traverses the TRLM and can be attached to a cable atvariable places along its length indirectly via the TRLM lever, etc. Seebelow. The cable, which traverses the proximal tube enters the handle ofthe device and interacts with the lever linkage. See below. As stated,in various embodiments, the components within the tube/shaft, e.g.cable, TRLM, toothed rod, etc., comprise stainless steel, while in otherembodiments they comprise a metal (aluminum, anodized aluminum, steel,magnesium, magnesium alloy(s), iron, or various alloys), plastics (e.g.,polyoxymethylene, Delrin, Lexan), polycarbonates, nylon, and/orcombinations thereof.

Head Region

As mentioned above, typical aspects and components of the head region,are applicable to a number of various embodiments of adjustable lengthdevices of the invention. Thus, for example, aspects of differentembodiments of head regions can optionally be paired with differentembodiments of handle regions (e.g., a handle region comprising alocking mechanism or a handle region not comprising a lockingmechanism). Relation of the head region with the other regions ofexample embodiments can be seen in, e.g., FIGS. 1 and 2, while variouscomponents of the head region can be seen in, e.g., FIGS. 3, 4 (showingan exploded view), and 5 (showing a cut away view).

At the distal end of the device (i.e., the end furthest from the handleregion and typically the region furthest from the user when held by thehandle) grasping jaw members, e.g., jaws 120, of the device oppose oneanother and form a modified “U” shape when open (e.g., when an object isnot being grasped) and form a five-sided or pentagonal shape when closed(e.g., when an object is being grasped or when the jaw members arebrought together without grasping an object). As explained more fullybelow, such shape can aid in grasping a wide range of differently sizedobjects. Additionally, the jaw shape and arrangement of the jaws (aswell as the surface layers, pads, etc.) add aesthetic interest to thedevice (e.g., through shape and optionally through colors and/ortextures of the various components, contrast in color/texture betweenvarious areas, etc.). The outer surfaces of the jaw members canoptionally be ridged or braced with one or more ribs or the like, e.g.,in order to strengthen the members. See, e.g., FIG. 1. In certainembodiments, the jaw members are constructed all of one piece. The jawmembers can also comprise an overmolded inner layer, or inner surfacelayer. See below. In certain embodiments, the distal end of each jawmember comprises end region or tip 111, which optionally can be attachedto the main body of the jaw member via flexible hinge 110. In otherembodiments, the tip is attached or connected to the main body of thejaw member via a nonflexible region, i.e., such embodiments do notcomprise a flexible hinge at the region where the tip and the main jawbody intersect.

In certain embodiments, the inner surfaces of the jaw members cancomprise inner surface layer 115, e.g., to aid in gripping of objects.The texture of the inner surface layer can be dimpled, roughened,ridged, striated, can comprise bumps or raised dots, or can comprise anyother three-dimensional surface texture. In certain embodiments, theinner surface layer comprises a flexible or malleable/conformablesurface. Thus, the inner surface layer can also conform at leastpartially to an object being grasped and thereby help prevent slippage,etc. whether or not the surfaces are “textured.” The inner surfacelayers can be composed of material having a high coefficient of frictionto aid in gripping of objects. Additionally, the inner surface layerscan comprise one or more coatings to aid in gripping of objects. Suchcoatings can also comprise those having high coefficients of friction orthe like.

In certain embodiments, the jaw members optionally do not comprise aninner surface layer. In other words, in such embodiments, the innersurfaces of the jaw members themselves grasp objects and the innersurfaces of the jaw members can be textured (e.g., dimpled, etc.) and/orcoated. Thus, in such embodiments, the jaw members can be textured ontheir inner surfaces rather than being mated with (e.g., throughovermolding or adhesion) another inner surface layer of texturedmaterial, etc.

When the jaw members are fully closed (e.g., when an object is beinggrasped or when the device is closed without grasping an object), padareas 105, can meet one another over substantially their entiresurfaces. In some embodiments, the pad areas can optionally meet/touchone another at their distal ends (e.g., when the jaws are broughttogether lightly or partially) and over substantially their entire areaswhen the jaws are brought together completely or more fully. It will beappreciated that the tips and pads of the jaw members allow grasping ofquite small objects and that the tips and/or the pads can optionallyflex and/or conform at least partially to the shape of objects beinggrasped. In certain embodiments, the pad area is continuous with, and/orpart of, the inner surface layer of the jaw member and can be composedof the same material. In certain embodiments, such material (i.e., whichcomposes the pad and/or the inner surface layer of the jaw member) canbe overmolded onto the jaw members, thus forming one solid piece foreach jaw member.

As stated, in certain embodiments, the inner surfaces of the jaw membersand/or the pads can comprise one or more overmolded pieces of materialthat comprise the inner surface layer. In other embodiments, the innersurface layers of the jaw members and/or the pads can comprise amaterial (e.g., comprising an inner surface layer, e.g., a texturedsurface), which is attached (e.g., via glue/adhesive or viastuds/brackets/pins/etc.) to the jaw member rather than overmolded.

The jaw members can optionally be constructed from a number ofmaterials. In certain embodiments, the jaw members comprise Lexan®(available from General Electric, Fairfield, Conn.), while in otherembodiments, the jaw members can comprise a polyoxymethylene such asDelrin® (available from E.I. du Pont de Nemours and Company, Wilmington,Del.). In certain embodiments, the jaw members can comprise metal (e.g.,aluminum, anodized aluminum, steel, stainless steel, magnesium,magnesium alloy(s), iron, metal alloys, and/or combinations thereof),plastic (e.g., a polycarbonate, a polyvinyl, a polyoxymethylene), athermoplastic, a thermoplastic rubber, a thermoplastic elastomer, etc.,ceramic, polymer, resin, wood, or any combinations thereof. In variousembodiments, the inner surface layers of the jaw members, and/or thepads, can comprise the same material as the jaw members or they cancomprise a different material than the main body of the jaw members. Inparticular embodiments, the inner surface layers can comprise one ormore of: a thermoplastic rubber (TPR), a thermoplastic elastomer (TPE),a silicon rubber, or a rubber. The composition of the inner surfacelayers and/or the pads is optionally chosen for one or morecharacteristic such as durability, gripping ability (e.g., a “no-slip”surface), aesthetic interest, etc. In certain embodiments, the innersurface layer and/or pads are textured and/or colored (optionally thesame as other parts of the device such as the trigger, palm area on theback of the handle, etc. (e.g., to add additional aesthetic interest).In some embodiments the inner surface layers and/or the pads compriseLexan, Delrin, metal (e.g., aluminum, anodized aluminum, steel,stainless steel, magnesium, magnesium alloy(s), iron, metal alloy(s),and/or combinations thereof), plastic (e.g., a polycarbonate, apolyvinyl, a polyoxymethylene), a thermoplastic, a thermoplasticelastomer, a thermoplastic rubber, etc., ceramic, polymer, resin, wood,or any combinations thereof. In some embodiments, the main body of thejaw members comprises polyoxymethylene, Lexan, or Delrin while the innersurface layers and the pads comprise TPR or TPE.

In certain embodiments, the jaws can open to a maximum distance of atleast 6 inches or more from tip to tip (e.g., from tip of pad to tip ofpad), to at least 5.5 inches or more from tip to tip, to at least 5inches or more from tip to tip, to at least 4 inches or more from tip totip, to at least 3 inches or more from tip to tip, to at least 2 inchesor more from tip to tip, or to at least 1 inch or more from tip to tip.

As can be seen in FIG. 3, proximal ends 305 of the jaw members (i.e.,the ends of the jaw members closest to the handle) overlap one anotherwithin jaw actuator (or clevis), 350. The proximal ends of the jawmembers enter through side openings 315 in the jaw actuator. The jawactuator keeps the proximal ends of the jaw members secure and in thecorrect orientation. The jaw members rotate around pivot points 300 (inthe jaw members) which optionally correspond with pivot points 125 (inthe jaw assembly) where bolts, screws, or other fasteners (such as pin410 and cap 400) secure and/or position the pivoting jaw members to thejaw base assembly. See FIG. 4.

The jaw actuator and the proximal ends of the jaw members are enclosedwithin jaw base assembly 130. The jaw base assembly comprises twoopposing sides 133 (shown as roughly triangular in the attachedfigures), separated by enclosing sidewall(s) 132. In certainembodiments, the jaw base assembly is molded or fashioned out of onepiece of material and is not constructed from smaller pieces. In someembodiments, the jaw base assembly can be composed of separate top,bottom, and sidepieces which are secured together (e.g., via glue,adhesive, fasteners, melting, welding, spot welding, etc.). Of course,it will be appreciated that such triangular shape should not necessarilybe taken as limiting on the invention and that the jaw base assembly canalso comprise different shapes (e.g., circular, square, oval, etc.) anddoes not necessarily have to have vertical side walls, etc.

The jaw actuator holding the proximal ends of the jaw members isattached, via jaw actuator cap 370 to jaw actuator rod 351 which, inturn, is surrounded by jaw actuator spring 360. Both the spring (e.g., acompression spring) and the rod are housed within the interior of thejaw base assembly. However, in some embodiments, the proximal end of thejaw actuator rod and/or the jaw actuator spring can extend into thehollow tube region of the device. See below. Also, it will beappreciated that in some embodiments, the jaw actuator cap does notcomprise a separate piece, but is rather a continuation of the jawactuator. Also, in some embodiments, the distal end of the actuator rod(e.g., end 450) is a separate piece, while in other embodiments, it ismerely an enlarged end of the actuator rod. The distal end of the springpushes against the jaw actuator (e.g., by pushing against the jawactuator cap), while the proximal end of the spring pushes against stopplate 500, or other similar plate, within the jaw base assembly. SeeFIG. 5. Because the spring pushes against both the jaw actuator and thestop plate, it forces the jaw members apart (i.e., away from oneanother) when the device is not being triggered (i.e., when the triggeris not squeezed and/or latched). See below.

While, as shown by the dashed motion lines in FIG. 1, the jaw memberscan move towards or away from one another, it will additionally beappreciated that in certain embodiments, the entire head region of thedevice can be rotated or pivoted around the elongated tube. See below.Such action can allow proper orientation of the jaws to grasp specificobjects. Cf. FIG. 1 and FIG. 2.

In various embodiments, one or more of the jaw actuator, jaw baseassembly, jaw actuator cap, jaw actuator rod, and spring can be composedof, e.g., metal (such as aluminum, anodized aluminum, steel, stainlesssteel, magnesium, magnesium alloy(s), iron, metal alloy(s), and/orcombinations thereof), plastic (e.g., a polycarbonate, a polyvinyl, athermoplastic, a thermoplastic elastomer, a thermoplastic rubber, apolyoxymethylene, Lexan, Delrin, etc.), ceramic, polymer, resin, wood,or any combinations thereof. In certain embodiments, the jaw actuator,jaw base assembly, jaw actuator cap, and jaw actuator rod are comprisedof plastic(s) (e.g., polyoxymethylene, Lexan and/or Delrin), while thespring is comprised of a metal (e.g., stainless steel, aluminum,anodized aluminum, iron, magnesium, magnesium alloy(s), steel, metalalloy(s), and/or combinations thereof). In some embodiments, the jawactuator, jaw actuator cap, jaw actuator rod, and spring are comprisedof metal (such as aluminum, anodized aluminum, steel, stainless steel,magnesium, magnesium alloy(s), iron, metal alloy(s), and/or combinationsthereof) while the jaw base assembly is comprised of plastic (e.g.,polyoxymethylene, Lexan and/or Delrin).

As explained in more detail above, the jaw actuator rod 351 is attachedto toothed rod 590 which traverses through adjustable length tuberegions 135 and 136 and is operably and controllably attached to cable(or in some embodiments, rod, strap, articulated strap, wire, chain, orother similar cable-like element) 660 via the TRLM. See above.

Handle Region

As can be seen in the accompanying figures, the handle region (region Cin FIG. 1) comprises a number of features and a number of differentembodiments (e.g., devices with or without a locking mechanism to holdthe jaws in place even when the trigger grip is not squeezed). Thehandle itself comprises a form designed to be grasped by the hand of auser. In certain embodiments, handle body 145 is comprised from a singlepiece of material, with handle cap 155 and trigger grip (or “trigger”)150, being attached to the single body of the handle. When present,optional latch lever 140 can also be comprised from a separate piece ofmaterial. Such single piece construction of the handle body can aid instrength and stability of the device. However, in other embodiments, thehandle body can be constructed from a number of pieces, e.g., twomirrored pieces which are fitted together and to which are attached thehandle cap, optional latch lever, and trigger grip, etc. In someembodiments, the handle comprises a hook or ring feature to allow thedevice to be hung or to have a cord/lanyard attached to the device(e.g., to allow the device to be hung). Thus, optional ring 165 is shownin the figures. FIGS. 1, 2 and 8 show the spatial relationship betweenthe handle region and the other regions of the device, while Figuressuch as 19-24 show various example components of different embodimentsof handle regions (e.g., embodiments comprising latching mechanisms inFIGS. 22-24 and embodiments that do not comprise latching mechanisms inFIGS. 20 and 21).

Trigger grip 150, (also referred to as trigger 150) in certainembodiments, comprises two mirrored pieces which are joined together(e.g., by adhesives, temperature setting or melting, friction forces,etc.) or are placed adjacent to one another, but not joined. Otherembodiments can comprise a trigger grip which is comprised of a singleformed piece. In either case, such trigger grip is typicallyergonomically shaped to allow for easy finger placement for the user andfor aesthetic style. Thus, as can be seen from the figures, the triggergrip can comprise raised ridges and depressions for finger placement. Itwill also be appreciated that the sides of the handle body(alternatively and/or in addition to the trigger) can comprise ridgesand other shapes to produce an ergonomic grip. The trigger grip attachesto the handle body at a pivot point (e.g., pivot point 2111). See, e.g.,FIGS. 20, 21, and 22.

In some embodiments (e.g., those comprising a latching mechanism), pivotpoint 2111 exists where the trigger is attached to the handle body. Atsuch point, a pin (e.g., pin 2103 and its corresponding pin cap(s) 2104)can be threaded through openings in the trigger grip pivot areas (e.g.,pivot areas 2208) to which the locking latches (e.g., latches 140) areattached. See, e.g., FIGS. 22 and 23. In other embodiments, e.g., thosethat do not comprise a jaw latching mechanism, a pin (e.g., pin 2103 andits corresponding pin cap(s) 2104) can also be used to pivot the triggergrip pivot areas around at pivot point 2111. See, e.g., FIGS. 20 and 21.In the various embodiments, when the trigger grip pivots from the pivotpoint, the base of the trigger grip slides into the body of the handlewhen the trigger is squeezed by a user. As will be appreciated, theinteraction of the handle and the trigger typically does not presentsharp edges or openings where a user's fingers could be pinched orinjured. As explained further below, when the trigger grip is squeezedand moves into the handle body, the linkage lever and the optionallatching lever are moved as well.

Also attached to the handle body is an optional latching lever (e.g.,lever 140). As mentioned, in embodiments where it is present, thelatching lever(s) are attached to a pin that threads through openings inthe trigger grip pivot areas (e.g., areas 2208) and the handle body atpivot point 2111. The latching lever(s) are placed on one or both endsof the shaft (i.e., on either one or both sides of the handle body). SeeFIG. 23.

The handle cap is attached at the base of the handle body. The cap(e.g., cap 155) is secured to the base via a screw (e.g., screw 2000),or similar fastener in various embodiments. However, in otherembodiments, the cap is attached to the handle body by adhesives,temperature setting, friction forces, etc. and optionally does notcomprise a screw or the like. In embodiments comprising a latchingmechanism, the handle cap optionally comprises a latch recess area(e.g., area 2410) into which the optional latch fits when the devicejaws are locked. See below.

In various embodiments, the handle body, handle cap, trigger grip, andoptional lever latch are comprised of or comprise, e.g., metal (e.g.,aluminum, anodized aluminum, steel, stainless steel, magnesium,magnesium alloy(s), iron, metal alloy(s)), plastic (e.g., apolycarbonate, a polyvinyl, a thermoplastic, a thermoplastic elastomer,a thermoplastic rubber, a polyoxymethylene, Lexan, Delrin, etc.),ceramic, polymer, resin, or any combinations thereof. In certainembodiments the handle body, handle cap, trigger grip, and optionallever latch are comprised of polyoxymethylene, Lexan, and/or Delrin. Inyet other embodiments, the handle body, handle cap, trigger grip, andoptional lever latch are comprised of a polyoxymethylene, Lexan and/orDelrin while palm rest area 160 (and optionally the trigger grip) alsocomprises an overmolded layer of thermoplastic rubber or thermoplasticelastomer for improved gripping, comfort, and/or aesthetics. In yetother embodiments, the palm rest on the back of the handle (andoptionally the trigger grip) comprises a thermoplastic rubber or athermoplastic elastomer.

As can be seen in the figures, the cable (e.g., cable 660) and thelinkage lever (which comprises upper linkage 2201 and lower linkage2203, which collectively comprise the leverage action mechanism) arealso comprised within the handle body. As stated previously, the cableis attached within the telescoping tube at its distal end to the TRLMand the TRLM lever. In the various embodiments, the proximal end of thecable enters the handle body, rests upon a roller or pin, traverses thelength of the interior of the handle, and attaches to the free end ofthe lower linkage lever at an attachment point (e.g., point 2180). Theend of the cable can be attached to the free end of the linkage levervia pin 2100, etc.

In particular embodiments comprising a locking/latching mechanism (see,e.g., FIGS. 23 and 24), the proximal end of the cable enters the handlebody, rests upon a roller (e.g., roller 2335) which optionally encirclesa pin (e.g., pin 2103) and which is between 2 wings or walls of alatching disc (e.g., latching disc 2375), traverses the length of theinterior of the handle and attaches to the free end of the lower linkagelever (e.g., at point 2180). In some such embodiments, the cable canrest directly upon the pin (e.g., pin 2103) rather than upon a rollersuch as roller 2335. As can be seen from FIGS. 23 and 24, the cable canbe kept in place on the roller (or pin) by sidewalls or wings of thelatching disc (e.g., disc 2375). FIG. 24 shows a transverse cut awayview of the area. In various embodiments, the roller on which the cablerests can be a separate piece from the latching disc or can be part ofthe latching disc. The latching disc is typically sandwiched between thetrigger grip pivot areas (e.g., areas 2208). See FIGS. 22 and 23.

In particular embodiments that do not comprise a locking/latchingmechanism (see, e.g., FIG. 21), the proximal end of the cable enters thehandle body, rests upon a roller (e.g., roller 2105) which encircles apin (e.g., pin 2103). The roller can comprise two wings (see FIG. 21)which help to keep the cable in place. In other such embodiments,however, the cable can merely rest upon the pin and be kept in place bythe trigger grip pivot areas (e.g., areas 2208). The cable traverses thelength of the interior of the handle, and attaches to the free end ofthe lower linkage lever at an attachment point (e.g., point 2180). Theend of the cable can be attached to the free end of the linkage levervia pin 2100, etc.

In the various embodiments herein (both with or without latchingmechanisms), the linkage lever is moveably hinged at the top (e.g.,2202) and middle (e.g., 2205), while free at the end (e.g., 2204)nearest the handle cap. In certain embodiments, pin 2101 and pin caps2102 can fasten the top of the linkage lever. See, e.g., FIG. 21. Incertain embodiments, the free end of the linkage lever moves within atrack or groove within the handle body or within the free space presentwithin the handle body. Thus, the lever is movable when the trigger gripis squeezed. When the grip is squeezed, pressure is applied by the gripupon the lever, which is pushed backwards and stretches out (e.g., freeend 2204 moves towards the handle cap at the base of the handle body),thus, pulling the attached cable (hence the trigger is a leverage actiontrigger). In certain embodiments (including embodiments either with orwithout latching mechanisms), the joint between the upper and lowerlinkages slides along a slope (e.g., slope 2440) on the inner wall ofthe trigger, thereby producing a smooth action of pulling on the cable.FIGS. 21, 23, etc. show cut away views of embodiments wherein the lowerlinkage lever comprises two mated, mirrored parts, through which thecable (cable 660) traverses. The various embodiments can also comprise aupper linkage lever that optionally comprises a single piece having aslot or opening through which the cable traverses or can comprises twomated mirrored parts. In other embodiments, the linkage lever cancomprise, e.g., 2 single pieces (rather than the doubled pieces shown inthe current figures) that are hinged and have the cable attached to thelower end, etc. FIGS. 19, 21, and 22 give various views/embodiments ofthe linkage lever in handle region of example adjustable length devicesof the invention.

Also within the handle body is the optional latching mechanism. Thelatching mechanism comprises latching lever 140, pin 2103 (which is alsopresent in the non-latching embodiments), latching disc 2375, roller2335, latching cable 2209, latch spring 2206, latch 2207, latch stopplate 2400, and latch recess area 2410 (actually created by recesswithin the handle cap, but used in latching action). As mentionedpreviously, the latch lever(s) (or latching levers) are present on theexterior of the handle body. Latch lever(s) 140, either on one or bothsides of the body, can be positioned “off” or “on” by the user eitherbefore, during, or after the trigger grip is squeezed (e.g., to grasp anobject). In certain embodiments, the latch lever can be locked “on”and/or “off.” In other words, the latch lever when locked “on” willallow the latch to function when the trigger is squeezed beyond acertain point. See below. When the latch lever is “off” the latch willnot function even when the trigger is squeezed beyond the requireddistance. See below. In certain embodiments, the locking of the latchoccurs by turning or pushing latching lever 140 past a designated point.In some embodiments, the body of the handle comprises a ridge, bump, orother protuberance (optionally comprised of the same material as thehandle body) positioned within the motion range of lever 140. Thus, insome embodiments, when the lever is pushed up, it will be forced abovethe ridge by the action of the user. In such instances, the lever willcatch on the ridge which will prevent the lever from moving backdownwards. Thus, in such example, the lever will be in an “off” positionand therefore the latching mechanism will not be able to be engaged.

At the bottom end of latch 2207 certain embodiments comprise a beveledor sloped edge. Such bevel/slope edge is on the side of the latch facingtowards handle cap 155, and allows for the latch to move more easily upand over the handle cap when the trigger is squeezed. Certain elementsof the handle cap also comprise a corresponding bevel/slope area 2200 aswell.

In various embodiments, the optional latch spring, latch cable, andcable comprise one or more metal (e.g., aluminum, anodized aluminum,steel, stainless steel, magnesium, magnesium alloy(s), iron, or variousalloys and/or combinations thereof). In some embodiments, the latchspring, latch cable, and cable comprise stainless steel. In variousembodiments, the latch lever, latch, pin (also referred to as latchingor latch lever shaft), latch stop plate, and latching disc comprisemetal (e.g., aluminum, anodized aluminum, steel, stainless steel,magnesium, magnesium alloy(s), iron, or various alloys and/orcombinations thereof), plastic (e.g., a polycarbonate, a polyvinyl, apolyoxymethylene, a thermoplastic, a thermoplastic rubber, athermoplastic elastomer, etc.), ceramic, polymer, resin, wood, or anycombinations thereof. In certain embodiments, the latch lever, latch,pin, latch stop plate, and latching disc comprise a polyoxymethylene,Lexan, and/or Delrin and the latch spring, (and optionally latch cable)comprise stainless steel. In some embodiments, the latch cable and/orthe cable comprise nylon. In some embodiments, the latch cable and/orthe cable comprises an articulated strap, strap, wire, woven wire,braided wire, chain, or other similar cable-like element

Exemplary Operation

The devices of the invention are capable of use in a number of ways andfor a number of methods. Thus, description of specific uses hereinshould not necessarily be taken as limiting. In certain embodiments, thedevice is held, via the handle within a user's hand, with the user'sfingers wrapped around trigger 150, and the user's palm against the backof the handle at palm rest 160. Again, as mentioned above, areas where auser holds the device can comprise material to help prevent slippage (aproblem of special concern with users who are elderly or who have poorgripping ability) and/or to present a decorative aspect (e.g., acontrasting color and/or texture). Thus, the palm rest at the back ofthe handle can comprise, e.g., an overmolded layer of rubber,thermoplastic rubber, thermoplastic elastomer, or the like. In someembodiments, the trigger can also comprise, thermoplastic elastomerand/or thermoplastic rubber (e.g., as an overmolded layer on, e.g.,polyoxymethylene, Lexan, Delrin, etc.). Some embodiments shown in thefigures comprise a stippled appearance in regions that are optionallycolored in various devices. See, e.g., FIGS. 22 and 24. Of course, itwill be appreciated that different embodiments can comprise differentcolors/textures/patterns/etc. in different areas of the devices in thedifferent embodiments. Such colors, etc., can add to the aestheticallypleasing shape of the devices. In additional embodiments, the device canfurther comprise a forearm brace running from the handle back along theuser's forearm to help support the device. Such braces are especiallyuseful for users having poor wrist strength. Also as mentioned above,the entire head of the device (i.e., region A in FIG. 1) can be rotatedin various embodiments in order to produce the proper angle forgrasping. See above.

As explained throughout, the length of the hollow tube/shaft of thedevice is adjustable. Thus, in use, the user will determine the properor desired length of the device, unlock or loosen the tube lockingmechanism (e.g., tube locking mechanism 137, e.g., by unscrewing it),pull or push the two pieces of the tube/shaft (e.g., tubes 135 and 136)together or away, and refasten the tube locking mechanism. Suchadjustment of the two pieces of the tube/shaft also positions thetoothed rod (e.g., toothed rod 590) a greater or lesser distance throughthe TRLM (e.g., TRLM 640).

Once the head is properly angled, the length is properly adjusted, andthe device is properly held, the user typically squeezes trigger 150 inorder to grasp an object. Squeezing the trigger pushes the linkage lever(e.g., linkage lever 2201/2203) back and down within the handle(optionally tracking along a slope such as slope 2440). The downwardmovement of the linkage lever pulls a cable (e.g., cable 660) which isattached to the free end of the lower linkage lever, e.g., point 2180,along with it. The cable, in turn, traverses the handle by going over aroller (e.g., roller 2335 or 2105) and pulls on the TRLM (e.g., TRLM640) by pulling on a lever within the TRLM (e.g., lever 1100). Thelever, in turn pivots and compresses a lever spring such as spring 1110.The lever thus engages its one or more teeth with a toothed rod (e.g.,toothed rod 590) thereby operably connecting the cable/TRLM with thetoothed rod. The toothed rod, in turn, pulls on a jaw actuator rod(e.g., actuator rod 351). The jaw actuator rod pulls on the jaw actuator(e.g., 350) by pulling on the jaw actuator cap (e.g., 370) and thuspulls the proximal ends (e.g., ends 305) of the jaw members (e.g., jaws120) back into the jaw base assembly while the distal ends of the jawmembers and jaw pads, pivot and are pulled towards one another.

When the trigger is released (assuming that the jaws have not beenlocked through use of the optional latching feature) the trigger nolonger pushes the linkage lever down into the handle. Thus, there nolonger is a force pulling on the cable so the TRLM lever spring is ableto disengage the TRLM lever from the toothed rod. Because the toothedrod is therefore free, the jaw actuator spring is able to push theproximal ends of the jaw members distally which pivots the jaw membersback open.

It will be appreciated that a wide range of different sized and/ordifferent shaped objects can be grasped by the device. Small objects canoptionally be grasped between the jaw pads on the end of the jaw memberswhile larger objects can be grasped between the pads or in the largerarea between the jaw members. As seen in the figures, the jaw membersare angled so that they encompass a wide opening between them. In someinstances when an object to be grasped is large enough to require thejaw members to be fully opened, the trigger can still be pulled back(e.g., far enough to allow latching in those embodiments comprising alatching mechanism, see below) and pressure applied to grip the object.In such instances, some embodiments of the device can optionally allowtrigger movement and applied pressure even without movement of the jawmembers (e.g., when the jaws are held to their greatest extension arounda large object), e.g., by play amongst the various cable/rod components,and/or by compression of the rod springs and proximal movement of thecable and TRLM, etc.

As will be appreciated, in various embodiments, the jaw members can bemoved (e.g., closed) over a greater distance than the distance that thetrigger is moved. Such embodiments allow for use of the device to graspa wider range of objects than would otherwise be possible. In someembodiments, the trigger can be moved, e.g., ˜1.5 inches while the tipsof the jaw members close, e.g., ˜5, ˜5.5, or ˜6 inches (e.g., thedistance between them). In certain embodiments, such ratio between thedistance the trigger is squeezed (moved) and the distance the tips ofthe jaws move can comprise about 1.5:5, 1.5:5.5, 1.5:6, 1.5:6.5, 1:5,1:5.5, 1:6, 1:6.5, 0.5:5, 0.5:5.5, 0.5:6, 0.5:6.5, etc. In variousembodiments, the tips of the jaw members move a greater distance thanthe distance moved by the trigger.

An optional feature in some embodiments of the device comprises alatching or locking system (a latching mechanism) which allows the jawmembers to be fixed in place (e.g., while grasping an object). Thisfeature can be especially important for users who cannot maintain aconstant grip pressure, thus allowing them to grasp an object, lock thejaw members, and not have to keep applying constant pressure on thetrigger. In some such embodiments, the locking action can engage nomatter the placement of the jaw members (e.g., jaws fully opened, jawspartially opened, jaws fully closed, etc.). To engage or disengage thelatching mechanism, which can be done before, during, or after graspingof an object, the user moves latching lever 140. As stated previously,in various embodiments, the lever can be present on both sides of thehandle body (see FIG. 23) or the lever can be present on only one sideof the handle body. To disengage the latch mechanism, in typicalembodiments, the latch lever is pushed upwards by the user (e.g., by theuser's thumb). Within the range of motion of the latch lever, variousembodiments comprise a ridge, bump, or other protuberance on the handlebody, which can be part of the handle body. See ridge 190 in FIG. 1. Incertain embodiments, the lever is flush or substantially flush with thebody of the handle so when it is pushed upwards, it is moved up and overthe ridge by force from the user. Additionally, and/or alternatively,the latch lever can comprise a ball bearing or opposing ridge on itsside facing the body of the handle, which ball bearing, ridge, orsimilar protuberance on the latch lever interacts with the ridge orprotuberance on the handle body. Once the latching lever is above theridge it tends to stay there until moved downwards by the user. Movementof the latch lever upwards, rotates the pin that the latching levers areoperably attached to (e.g., pin 2103) and the latch disc (e.g., 2375)and optionally the roller (e.g., roller 2335 when present). Suchrotation pulls on the latch cable (or strap, etc.) 2209 which pullslatch 2207 upwards. If the latch is pulled upwards, then even when thetrigger is squeezed and moves into the body of the handle, the latchwill not be able to extend downwards into recess area 2410 in order tolatch the jaws.

In uses when the user desires to engage the locking mechanism, latchinglever 140 is not pushed upwards (or is pushed downwards below theridge/protuberance if it the latching lever is above such). Thus, whenthe trigger is squeezed and moves back into the body of the handle,latch 2207 (which can be sloped/beveled on the bottom) moves up and intothe body of the handle over area 2200. When the trigger is squeezed farenough back, the latch is pushed down into recess 2410 by action oflatch spring 2206. The latch spring pushes against latch plate 2400 andthe top of the latch. When the latch is moved in position above thelatch recess, the latch spring (e.g., a compression spring) pushes thelatch into the recess where it catches on the interior of the handle capand thus “locks” the trigger in place. Since the trigger is locked inplace, it therefore causes the linkage lever to be locked in place,which in turn causes the cable and toothed strap to be locked in place,which causes the jaw members to be locked in place. To release the lock,users can move the latching lever upwards. See above.

As stated previously, the locking mechanism can be engaged (when it isswitched “on”) no matter the size of the object being grasped. Forexample, if a small object is to be grasped between the tips/pads of thejaw members or if a large object is to be grasped between the mainbodies of the jaw members so that the jaws are at their widest, the jawscan still be latched. In either instance, the trigger is squeezed untilthe object is grasped. In some embodiments, the amount of triggersqueezing necessary just to grasp the object can be enough to push thetrigger, and hence the latch, back far enough into the handle so thatthe latch is capable of engaging and locking the trigger (if the latchis “on”). However, the current invention also optionally provides thatonce an object is grasped (and, thus, the jaws held a certain distanceapart), the user can still squeeze the trigger far enough into thehandle to engage the latch no matter the size of the object held. Thisis optionally because of play within the various connected components invarious embodiments, or by compression of the rod springs and proximalmovement of the cable, etc. Such expansion/stretch, thus, allows thecable and toothed strap, etc., to move proximally and the trigger to bemoved far enough into the handle so that the latch is engaged (when itis “on”) no matter the size of the object being held.
